The answers to the questions are:

1. x = 4

2. x = 1.5

3. x = 1.875

4. x = 1

<h3>2 step equation:</h3>

1. 4x + 3 = 19

4x = 19 - 3

4x = 16

divide by 4

x = 4

<h3>2 step equation w/ fractions:</h3>

(4/3)x + 5 = 17

= 1.33x + 5 = 7

Take like terms

1.33x = 7-5

1.33x = 2

divide through by 1.33x to get 2

x = 2/1.33

x = 1.5

<h3>3. Distributive Property:</h3>

4x(6 - 2) - 10 = 20

Multiply and open the bracket

24x - 8x - 10 = 20

Take like terms

16x = 20+10

16x = 30

x = 30/16

= 1.875

<h3>4. Decimals:</h3>

4.3x + 0.7 = 5

4.3x = 5 - 0.7

4.3x = 4.3

x = 1

Solve the following system of linear equations: 3x1+6x2+6x3 = -9 -2x1–3x2-3x3 = 3 If the system has infinitely many solutions, y

choli [55]

Answer:

The set of solutions is $\{\left[\begin{array}{c}x\\y\\z\end{array}\right]=\left[\begin{array}{c}12\\-7-r\\r\end{array}\right]: \text{r is a real number} \}$

Step-by-step explanation:

The augmented matrix of the system is $\left[\begin{array}{ccccc}3&6&6&-9\\-2&-3&-3&3\end{array}\right]$ .

We will use rows operations for find the echelon form of the matrix.

In row 2 we subtract $\frac{2}{3}$ from row 1. (R2- 2/3R1) and we obtain the matrix $\left[\begin{array}{cccc}3&6&6&-9\\0&1&1&-7\end{array}\right]$
We multiply the row 1 by $\frac{1}{3}$ .

Now we solve for the unknown variables:

$x_2+x_3=-7$ , $x_2=-7-x_3$
$x_1+2x_2+2x_3=-2$ , $x_1+2(-7-x_3)+2x_3=-2$ then $x_1=12$

The system has a free variable, the the system has infinite solutions and the set of solutions is $\{\left[\begin{array}{c}x\\y\\z\end{array}\right]=\left[\begin{array}{c}12\\-7-r\\r\end{array}\right]: \text{r is a real number} \}$

This bar graph shows the number of hurricane in the Atlantic Basin from 2006-2011. Find the amount of change and the percent of

Arada [10]

Answer:

Step-by-step explanation:

Number of hurricanes in year 2008 = 8

Number of hurricanes in year 2009 = 3

Decrease in number of hurricanes = 8 - 3 = 5

Percent of decrease in number of hurricanes = $\frac{5}{8}\times 100$ = 62.5%

Number of hurricanes in year 2010 = 12

Number of hurricanes in year 2011 = 7

Decrease in number of hurricanes = 12 - 7 = 5

Percentage decrease in number of hurricanes = $\frac{5}{12}\times 100$ = 41.7%

Decrease in numbers of hurricanes in year 2010 - 11 was same as in year 2010 - 11.

Percentage decrease in hurricanes were more in year 2008 - 09 than percentage decrease in year 2010 - 11.
